I connected Siemens CFX65 to PC via com-port(RS232) for evaluating data exchange and I see: >at OK >AT+CGDCONT=1,"IP","mms.my-mmsc.com" OK >ATD*99***1# CONNECT (there are hex-reps of incomming bytes): 7E FF 7D 23 C0 21 7D 21 7D 21 7D 20 7D 33 7D 22 7D 26 7D 20 7D 20 7D 20 7D 20 7D 23 7D 25 C2 23 7D 25 7D 27 7D 22 7D 28 7D 22 57 7D 30 7E 7E FF 7D 23 C0 21 7D 21 7D 21 7D 20 7D 33 7D 22 7D 26 7D 20 7D 20 7D 20 7D 20 7D 23 7D 25 C2 23 7D 25 7D 27 7D 22 7D 28 7D 22 57 7D 30 7E 7E FF 7D 23 C0 21 7D 21 7D 21 7D 20 7D 33 7D 22 7D 26 7D 20 7D 20 7D 20 7D 20 7D 23 7D 25 C2 23 7D 25 7D 27 7D 22 7D 28 7D 22 57 7D 30 7E NO CARRIER What is it? I suppose I must establish connection with MMSC, but what protocols can I use? Is it WSP/WTP datagram (WAP-230/WAP259)? | |||

Sorry, this is the technical support forum for the Now SMS/MMS Gateway product. I have to give my priority attention to responding to technical support queries regarding our products. To give a very brief answer, after the modem reports "CONNECT", there must be a PPP negotiation to establish a TCP/IP link. The MM1 protocol for MMS is used, which uses the MMS Encapsulation format defined by the Open Mobile Alliance. In many environments, MMS messages are transmitted over WSP/WTP/WDP, while sometimes HTTP is used. Either way, when an MMS notification is used to deliver an MMS message to a mobile phone, that part uses WAP push over WSP/WDP (connection-less push bypasses the WTP layer). -bn | |||
